Although I have mentioned, I am not NASM expert. They are a ton of great resources to get you learning NASM. The list is not exactly comprehensive, and please understand this page is for learning NASM and not the development environment
itself. In addition, I do not endorse these sites any way. If you have any links to great NASM resources go ahead post them here or message me.

Nothing to do with the development environment itself. Another wiki page will be specifically on NASM and NASM Develop IDE.

Resources can be either internal or external. But try to avoid direct download links (PDF and other document formats might be okay). It is best if it is web based, so that the user doesn't risk getting infected by downloading stuff.
